They are stableenough on voltammetric time scale for furthermanipulations.The objective of this research is to investigate the solvent and temperature dependence of first reduction process, to study the protonation of the first reduction products of dinitrobenzene and to measure the heterogeneous electron transfer rate constants in HMPA solvent at different temperatures.The substrates are the three isomers of dinitrobenzenes and the protonating agents are benzoic acid and salicylic acid.
